This post will be dedicated to a kit that I recently produced. Last year, I wanted to do a 3D Printed Model of the NSWGR Precast Platform for a working Diorama type layout which was best done as a 3D print out produced from Shapeways. However, the down point of this approach is that the cost to make the standard short length of this platform would be very high and the longer length version would have almost been doubled which would have been very questionable if it was worth doing this project at all. Therefore, I got the 3D Prints on certain parts of the platform and created a casted model kit out of them.
The following is an instructional steps on how I produced this platform, Instructional steps on how to build up this platforms and a bit of historical background on these platforms.
Development Of The NSWGR Precast Platform Kit
To address the challenge of preventing this model to exceed reasonable costs, but also could be easily reproduced for other projects. With also the flexibility to make desired lengths and be able to be profiled also to be a Curbed Platform (like the case at Robertson Railway Station), I have 3D drawn up and got printed several different platform parts to be able to construct a Platform.
These parts have been made to be able to be casted and produced into not just a simple kit that someone at beginner level and beyond can build up, but ends up being completed into a solid neat looking item that can be placed on your Layout.
Building the NSWGR Precast Platform Kit
My first build of this platform took me one night to assemble, paint and to weather it up.
What is needed are the casted up platform pieces, a ruler (Preferably a Steel Ruler), Super Glue, (Optional) Styrene strip (Ideally anything above 2.5 mm x 2.5 mm styrene strips), Primer, Paints and weathering items (what works best for you to your method of painting and weathering). I will share the details of paints and weathering methods that I used for this platform build.
Also a file will be needed to remove any exceed flushing from the casting and remove any obstructions that may prevent a flush connections between the platform parts.
I used Loctite Gel Control Super Glue that I got from Bunnings to join the Pieces of Platform together and to glue on the styrene strip on the back of the platform to assist with holding in the Pieces of Platforms together which also makes the platform rigid. Styrene strip does not have to be used, but without it you can run the slight risk of the platform breaking apart when moving it around when fitting it onto your layout.
The Ruler helps allow the platform pieces join together straight and square to one another.
